DCMT 11T304 AH6225 turning insert by Tungaloy — PVD-coated carbide, ISO series

DCMT11T304 AH6225 is an ISO-format indexable turning insert designed for external and internal turning, offering a universal grade for variable machining conditions.

• PVD-coated carbide grade AH6225
• Optimised for stainless steels
• 55° rhombic insert geometry
• 0.4 mm corner radius

Consistent performance for medium turning of stainless steels

The PVD-coated carbide composition AH6225 is engineered as a universal grade for machining stainless steels, providing a balance between a sharp cutting edge and robust edge stability. This combination reduces the risk of built-up edge and extends effective cutting periods during medium-duty operations. The indexable design from the ISO series ensures repeatable seating and predictable wear patterns, which supports process reliability and lowers unexpected downtime. The result is a more efficient machining cycle with consistent part quality.

Geometry and tolerances that simplify set-up

The 55° rhombic geometry with a 7° relief angle and a 0.4 mm corner radius gives a compact but rigid cutting profile that is suitable where a compromise between clearance and edge strength is required. The insert’s geometry reduces vibration in less rigid set-ups and improves surface finish on a wide range of rotating parts. Compatibility with ISO holders is determined by form, relief, tolerance class, fastening and thickness, which helps to standardise inventory and simplifies toolholder selection for workshops following ISO tooling conventions.

System integration and longer tool life

As part of an ISO-indexable system, the insert works with a matching external holder or boring bar, plus the relevant clamping set and replacement screws. The single-sided chipbreaker evens out chip formation under varying operational conditions and supports controlled chip flow, which contributes to prolonged insert life. Choosing a universal grade such as AH6225 helps when the production mix includes different stainless-steel alloys, reducing the need for frequent insert changes and improving overall process economy.

Practical handling, inspection and replacement

The insert features a central hole with a cylindrical bore and a single-sided countersink (40°–60°), enabling secure clamping and straightforward indexing. Regular inspection of the cutting edge for flank wear and chipping informs replacement intervals; this insert’s PVD coating helps resist abrasive wear, while the substrate maintains toughness. For workshops aiming to maintain steady throughput, the combination of coating, geometry and ISO conformity translates into predictable performance and easier planning of spare parts.

FAQ

What materials is this insert suited for?
The DCMT11T304 AH6225 insert is designed as a universal grade for stainless steels, with the PVD-coated carbide substrate offering wear resistance and a reliable cutting edge for medium turning tasks.

Is this insert compatible with standard ISO holders?
Compatibility is determined by the insert’s form, relief, tolerance class, fastening, size and thickness; the DCMT11T304 conforms to ISO-series specifications and fits holders designed for the DCMT 11 format.

How does the chipbreaker influence machining?
The single-sided chipbreaker on the DCMT11T304 promotes controlled chip formation under varying cutting conditions, improving chip evacuation and contributing to longer insert life and more consistent surface finishes.

What does the 0.4 mm corner radius mean for finishes and strength?
A 0.4 mm corner radius gives a compromise between a fine surface finish and a robust cutting edge; the DCMT11T304’s geometry helps reduce edge chipping while maintaining acceptable surface quality in typical turning applications.

Which components complete the tool system for this insert?
The system comprises the ISO-indexable insert itself, a matching external holder or boring bar, an underlay/clamp set and replacement screws; correct assembly ensures stable clamping and repeatable tool performance.
